This ^^^^ so true.
I used to have my own independent site, but maintaining it was a huge pain. I always redirect clients to my facebook page, where its easy to look through an album of art and its got links to all the places where my comic is hosted/mirrored.
I've never had a problem getting published or finding clients, even though I don't have a site. I think its really up to the individual and who you are targeting for work.
Quite honestly if you are asking publishers to accept your work, you should be sending them the work directly (like a printed portfolio, ebook, or digital file). I guarantee no editor wants to click through a bunch of links or go looking for your art.
So, in my opinion, its up to the individual artist and how you want to market yourself.
